This 4 slip-on flange is 304 Stainless Steel with a raised face face in 150#. If youÕve ever needed to bolt pipe to a valve or piece of machinery, this slip-on flange is the part that makes that connection possible. ItÕs commonly selected for general service applications and everyday plant use. The raised-face sealing surface is designed to mate well with common gasket styles used on stainless systems. Slip-on flanges slide over the pipe, which can make alignment easier during fabrication and installation. TheyÕre widely used because they simplify fit-up before weldingÑhelpful when youÕre working on a tight schedule.
